Question

The apparent coefficient of expansion of liquid, when heated a copper vessel is `C` and when heated in a silver vessel is `S`. If `A` is the linear coefficient of expansion of Copper, linear expansion coefficient of silver is
A. `(C + S - 3A)/(3)`
B. `(C + 3A - S)/(3)`
C. `(S + 3A - C)/(3)`
D. `(C + S + 3A)/(3)`

Answer 1

Correct Answer - B
For copper vessel `gamma_(R) = (gamma_(A))_(c) + 3alpha_(c)`
For silver vessel `gamma_(R) = (gamma_(A))_(s) + 3alpha_(s)`
